It would be nice to be able to go to a user, look at the pages and cards they have access to, select all, and share with a new user that's being set up. I know groups is a good way to manage access easily and efficiently, but sometimes it's nice to be able to mass mimic access at the dashboard and card level, especially when Groups isn't the best way to do this. It would also be nice to be able to view what datasets the person has access to on the People tab, and do the same thing there. It would be an easy functionality to add that would help save a lot of time.
